MRI uses the
principles of nuclear magnetic resonance, creating images of the body
from radiofrequencies given off by the body. Today's MRI machines use
very strong magnetic fields (many times stronger than the earth's
magnetic field) to allow the human body's hydrogen atoms to give off
radiofrequencies that the MRI equipment detects much like a radio. The
MRI room is surrounded by a copper Faraday cage preventing outside
signals (such as radio and T.V. signals) from entering the room. The
radiofrequency signals emanating from your body are placed in the
proper anatomic position, using very sophisticated computer models.
MRI images are some of the most elegant and accurate anatomic images
available of the human body.
IDI provides OPEN MRI. This
open architectural design provides an environment which lessens
claustrophobic tendencies in most patients. For Appointment Call (850) 314-7575.
Clinical Uses for MRI:
Neurological
MRI provides the most sophisticated and elegant visualization of the
brain and spine available. These studies are usually performed without
injections or other invasive procedures. Occasionally, depending on
the patient's medical problem, an injection helps us visualize more
with MRI.
Musculoskeletal (Sports Medicine)
MRI is the best way to visualize all joints of the body and the
adjacent muscles, tendons, and ligaments. This is particularly helpful
with sports-related injuries.
Body Imaging (Chest, Abdomen, and Pelvis)
The latest MRI equipment enables visualization of the many anatomic and pathologic processes in
the abdomen and chest procedures. MRI is replacing invasive
procedures, such as angiography and evaluation of the gallbladder and
biliary ducts (ERCP's, etc.).
Contraindications:
MRI is a convenient and safe diagnostic procedure; however, certain
contraindications do exist. Because MRI utilizes a high magnetic
field, patients with metal objects in the body can pose a
contraindication. Absolute contraindications (these patients should
never receive a MRI) include cardiac pacemakers and brain aneurysm
surgical clips. You should notify your technologist or physician if
you feel these may be an issue for you.
Orthopedic hardware, such as total joints, is not a contraindication
to performing the MRI. A MRI exam may be uncomfortable for patients
who are severely claustrophobic. If this is a concern of yours, please
inform our staff.. |
